Cover from Poland








On the 10-th of January after 8 days of travelling I got the next excellent cover from Andrzej! This time it was the stamps devoted to the outstanding Polish people. It's one of my favourite topic for it helps me to know more about science and technology developing.




Here is some information about the figures of the stamps:




Monocrystals and metal B
Jan Czochralski (1885-1953) - a specialist in metallurgy and inventor of the presently universal method of obtaining silicon monocrystals known as the Czochralski method (or the Czochralski process), and a method of metal recrystallisation. Having graduated from a Teacher's College he left to Berlin in 1904 where he worked on determining the quality and purity of metals and copper refining. He attended lectures on specialised chemistry in Charlottenburg at the local technical university, following which he started his own academic career. Among others, he studied the properties of light metals and in 1924 he patented what is known as metal B, a bearing alloy used in Europe and in the United States in the railway industry. Following his return to the country in 1929 he became a professor at the Institute of Chemistry at Warsaw University of Technology. The silicon monocrystals, obtained with the Czochralski method, are presently used in the production of microchips.


Blood types and the serologic conflict
Ludwik Hirszfeld (1884-1954), a doctor, microbiologist and serologist, creator of the Polish school of immunology and a novel branch of science called seroanthropology. Following his medical studies in Germany he worked as assistant in the Cancer Studies Institute in Heidelberg. He also worked in the Institute of Hygiene in Zurich ( Switzerland). He studied the problems of human immunology and blood coagulability. He returned to Poland in 1918 where he carried on his research. His most outstanding achievements are his works on blood types, including the law of blood type succession and their marking (developed in cooperation with Emil von Dungern) as 0, A, B, and AB, which is in use to date, and also the marking of the Rh factor and the discovery of the reasons for the occurrence of the serological conflict. Additionally, he co-founded the National Institute of Hygiene (Państwowy Zakład Higieny) in Warsaw and the Maria Curie-Skłodowska University in Lublin (UMCS) and also established the Polish Academy of Sciences Institute of Immunology and Experimental Therapy (Instytut Immunologii i Terapii Doświadczalnej PAN) in Wrocław and the Research Centre for Pregnancy Pathology (Ośrodek Badań Patologii Ciąży). He was a university professor in Warsaw and in Wrocław.


The best watches in the world
The Polish watchmaker that gained the highest renown in the world was Antoni Norbert Patek (1812-1877). He was awarded the Golden Cross of the Virtuti Militari Order for his participation in the November uprising. Following the defeat of the insurgency, he emigrated to Prussia, and from there he went to France. After long journeys he settled in Geneva, Switzerland, where in 1839 he set up a small factory of watches in stylish casing together with Franciszek Czapek. In 1844 he met the famous French watchmaker Adrienne Philippe, inventor of the "remontoire" spring drive. A year after, the two friends together established the company Patek-Philippe, which exists to date, and launched the mass manufacture of pocket watches, followed by wrist watches later on, known for their excellent quality. Presently the company's watches are a paragon of quality and artistic design.


The secret of the Enigma


The outstanding Polish mathematicians and cryptologists Marian Rejewski (1905-1980), Henryk Zygalski (1907-1978) and Jerzy Różycki (1909-1942), working in the Decrypting Centre at the Main Staff Sheriffs' Office of the Polish Army in Pyry near Warsaw, succeeded in creating a replica of Enigma, the German encrypting machine used to ensure full secrecy of wartime messages. The Polish Army then delivered copies of the machine to similar centres in Great Britain and France, where the researchers were evacuated following the outbreak of World War II. The breaking of the Enigma's code and the resulting possibility of mechanical decrypting of hundreds of German messages containing precise operational plans and military orders contributed to the allied victory in the war. Sadly the British, who the Polish cryptologists cooperated with, took all the credit for the success. For many years Poles fought for their due recognition.


Dziękuję, Andrzej!

Cover from Italy



On the 8-th of January after I don't know how many days of travelling (the stamps weren't cancelled, but still I think after a long time of travelling for the letter was dated by the 13-th of Dec) I got the next cover from Italy, devoted to the series "made in Italy" Isn't it beautiful? 

A yellow gold and platinum necklace with amethysts, turquoise stones, emeralds and diamonds, created by BVLGARI in 1965 and belonging to the BVLGARI Vintage Collection; at the top in the middle is the firm’s trademark.
The words “MADE IN ITALY“, “125 ANNI” (125 years), “ITALIA”, and the denomination “€ 0,60” complete the stamp.

Thank you, Lorenzo!

Big cover from Slovenia






On the 8-th of December after 16 days of travelling (well it's not 23 like it was last time) I got this amazing cover from Slovenia. I was waiting for the English version of the Slovenian Post page to appear but it's still only on Slovenian, so I'll try to descibe them using the similarity of slavic languages.

Ok, the first stamp is devoted to the 10-th anniversary of using Euro as the currency of many countries in the EU. The number of them is growing every year. It's very difficult to estimate this event unambiguously for it should have negative and positive aspects, but I belive that the positive aspects are prevailed for at least it makes people life easy in the way of having the same currency in many countries. So you don't have to exchange your money everytime you are in another country, waisting your time and money!

The stamp with the man and a horse is from the series "means of conveyance". In 2008 it was devoted to a sleigh. The stamp is called "A sleigh for goods transportation" and is oriented to show us the tradion of a sleigh use in Slovenia.

I didn't find any concrete information about these low value (0.12 € and 0.13 €) stamps for it wasn't possible to allocate the year of issue (it's not 2008 neither 2009). As I understood, all of them are from the "Red cross" series; the 0.12 € stamp is devoted to the week of solidarity - 1-7 of November 2008 and the 0.13€ is devoted to the idea of Red cross organization's creation which was occured in the 1859.

And of course, there is the other addition to my Euro cept collection! There are 2 stamps devoted to this series. This one is devoted to the 50-th anniversary of the "Golovec" observatorium opemimg.

Thank you very much, Kristijan for that cover!
